Urban Planning / Transport

At the urban scale, integrating LASA’s expertise at the earliest stages of projects enables optimised management of noise impacts arising from planning decisions, in synergy with other constraints such as solar exposure, accessibility, and transport services.

Indeed, assessing environmental sound quality within urban blocks or eco-districts makes it possible to optimise the master plan in order, on the one hand, to improve the “liveability” of future occupants (mixed land use, management of balanced acoustic environments, etc.), and on the other hand, to rationalise construction costs. LASA therefore provides 3D acoustic modelling to support decisions regarding building orientation relative to one another and to noise sources, the functional organisation of buildings, and the preservation of quiet zones.

Acoustic and vibration studies (in situ measurements, predictive modelling, dynamic noise mapping, etc.) make it possible to anticipate the impact of existing or planned transport infrastructure (road, rail, and air networks) on urban development projects. LASA’s 3D models contribute to optimising alignments, sizing and optimising mitigation measures (source treatments, noise barriers, anti-vibration cut-offs, reinforced façades, etc.).
